The tag looks original to me. It's an ordinary vehicle (not an X22, X33, X77) and those are the ones that seem to come up as fakes. I've never noticed the 'V' in the first line, but I tend to look more at 68 tags.

I can't comment on the trans. IMO - The block stamp looks good. The VIN ...hmm, I would lean towards questionable, also (but I haven't seen any stamps from this build period). I, too, would like see it without all the paint and would like a better pic of the trans, Attached is a couple of pics of my former 02A LA built Z (man, I miss that car )
